(1) The workability of refractory plastics. -Generally, it is required that the refractory plastics should have high plasticity, and still after long-term storage has a certain degree of plasticity. If the plasticity of the refractory plastic is not significantly reduced during its storage period, hydraulic binders cannot be used. If air hard for the sex binder, … Read more
Refractory plastic is made of powder and granular materials, plastic clay and other binders and plasticizers, add a small amount of water, after sufficient mixing, it is composed of a kind of unshaped refractory that is in the form of hard mud and maintains high plasticity for a long time. Granular and powdered refractory materials are … Read more
Refractory Castable is currently the most widely produced and used unshaped refractory material. Mainly used to construct various heating furnaces lining and other overall structures. Certain high-quality varieties can also be used in smelting furnaces. For example, alumina cement castables can be widely used in various heating furnaces and other thermal equipment without slag and acid … Read more
What five type of high alumina brick use in industry furnace? High alumina brick refers to aluminosilicate or pure alumina sintered products containing more than 348% Al2O. Generally, high alumina bricks contain less than 80% Al2O3, and those containing more than 80% Al2O3 are called corundum bricks. Compared with clay firebricks, high alumina bricks have … Read more
The size of the high alumina refractory brick is the value indicating the length, width and height of the refractory brick, generally expressed in mm. What are the sizes of refractory bricks? According to the masonry principle, there are general high alumina brick dimensions inches and special-shaped custom refractory bricks. High refractory brick manufacturers can customize … Read more
Silicon carbide bricks have high thermal conductivity, good wear resistance, thermal shock resistance, and corrosion resistance. Therefore, silicon carbide bricks are widely used in industry furnace linings. It can be used for metallurgical steel cylinder lining, nozzle, plug, blast furnace bottom and hearth, heating furnace without water-cooled slide rail. Non-ferrous metal smelting distiller, rectification tower … Read more
Refractory concrete is made up of refractory aggregates, powders, and cement, added with water or other liquids and is an unshaped refractory material used directly without calcination. Refractory concrete and refractory castables belong to the category of unshaped refractory materials. There are hundreds of refractory castables and they are widely used. So, what are the … Read more
Although there are many types of industrial furnaces, in terms of basic structure, they mainly include three parts. ①The heating system, which includes the equipment system that provides various heat sources to the materials in the industrial furnace. For example, energy medium pipelines and equipment systems, power transmission system transformer equipment, etc. ②Industrial furnace body, … Read more
The alkali vapor corrosion of refractory materials is mainly related to the pore structure and chemical composition of the material. The pore structure mainly affects the penetration process of alkali vapor, while the chemical composition affects the chemical reaction process in the erosion process. Therefore, the method to improve the resistance of refractory materials to … Read more
The basic material composition of ordinary refractory ramming materials is basically similar to refractory castables and plastics, and it is also composed of refractory aggregates, powders, binders, and additives in proportion. The difference between them is that the amount of powder in the ramming material is more, and the amount of binder is less. Soft … Read more
